JOSEPH HERM, OF LOS ANGELES, CALIFORNIA.

RAILWAY-CROSSING.

Application filed October 17, 1916.

1 '0 all whom it may concern:

Be it known that I, JOSEPH HERM, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles, State ofCalifornia, have invented new and useful Improvements inRailway-Crossings, of which the following is a specification.

This invention relates to new and useful improvements in crossings forrailways and consists in the provision of a safety means whereby it willbe necessary to cause mechanism to be actuated to throw rotary grooveddisks into alincment with the grooves of the rails before crossings maybe effected.

My invention comprises various details of construction, combinations andarrangements of parts which will be hereinafter fully described, shownin the accompanying drawings and then specifically defined in theappended claim.

I illustrate my invention in the accompanying drawings, in which Figure1 is a top plan view.

Fig. 2 is a sectional view on line 22 of Fig. 1, looking in thedirection of the arrows.

Reference now being bad to the details of the drawings by letter, Adesignates a crossing which may be of a single piece or made up of aplurality of rail sections, having grooves B for the reception offlanges. At the intersecting points of the rails are circular outlinedopenings in which are rotatably mounted the disks C, having shankportions with their lower ends tapering as at E, as shown clearly inFig. 2 of the drawings, and which have bearing in tapering indentures Fformed in the bosses H. Upon the circumference of the shank portion ofthe rotatable disk is a sprocket wheel I, and T is an indenture formedin the shank portion of the disk and adapted to be en- Specification ofLetters Patent.

gaged by the pointed pin R which is thrown to its outer limit throughthe medium of the spring S mounted in a hole formed in the wall of thechamber in which the disk is mounted. Said disk has a transverse grooveD formed in the outer face and which is of a width equal to the width ofthe groove B into which it is adapted to be thrown into registration topermit the wheels of a truck to cross.

A sprocket chain 0 is mounted about said sprocket wheels I and passesbetween the idlers L, shown in Fig. 1, which chain may be attached toany suitable means, either manually operated or power controlled wherebythe several disks may be thrown in unison to cause the grooves in thedisk to register with the flanged grooves in one track or the other.

What I claim to be new is A railway crossing comprising intersectingtrack sections, having grooves for the flanges of wheels,circular-outlined chambered portions at the intersection of the rails,rotatable disks mounted in each chambered portion and each having atransverse groove adapted to be thrown into registration with thegrooves of said rail sections, sprocket wheels rotating with said disks,a sprocket chain passing about the sprocket wheels and adapted to movethe same in unison, and a spring-pressed pin for engagement with andadapted to hold the disks in set position.

In witness that I claim the foregoing I have hereunto subscribed my namethis 25th day of July, 1916.

JOSEPH HERM.
